I'm glad to have found this thread. I was able to install RHL 6.2 using KVM but I have a quick question. I'm getting the interrupt errors mentioned at the beginning of the thread during boot time. I know I can append ide=nodma and re-install grub once the instance is up, but it seems to be taking a ridiculous amount of time to boot to a point where I can do this. Is there a way to pass a kernel boot time option with LILO or do I just have to wait until the box can come up? I have tried: linux ide=nodma linux append=ide=nodma at boot but no luck. Any help would be greatly appreciated!

Re: Has anyone tried to run Linux 2.2 under KVM?
Hey guys, I was able to boot the instance with Knopix and add the append=ide=nodma line which got me up and running but the instance seems to lock up frequently. I'm wondering if there are some kvm tweaks I can make to stabilize the system. Here is what my qemu-kvm options look like: /usr/libexec/qemu-kvm -S -M rhel5.4.0 -cpu qemu32 -m 256 -smp \ 1,sockets=1,cores=1,threads=1 -name RHL6 -uuid \ 0be67ae0-2544-a356-05c0-1e3550681760 -monitor \ unix:/var/lib/libvirt/qemu/RHL6.monitor,server,nowait \ -no-kvm-pit-reinjection -no-acpi -boot c -drive \ file=/var/lib/libvirt/images/vm_lun_1 \ rhl6.img,if=ide,bus=0,unit=0,boot=on,format=raw -drive \ file=/media/redhat-.2- \ i386.iso,if=ide,media=cdrom,bus=1,unit=0, \ readonly=on,format=raw -net nic,macaddr=54:52:00:48:07:00, \ vlan=0,model=ne2k_pci -net tap,fd=23,vlan=0 -serial none \ -parallel none -usb -vnc 127.0.0.1:2 -k en-us \ -vga cirrus -balloon virtio Thanks again! -Arthur -- To unsubscribe from this list: send the line unsubscribe kvm in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Has anyone tried to run Linux 2.2 under KVM?
I've been trying out RHL6.2 [sic] on KVM 70. This has an ancient 2.2.14 kernel and generally dates from 1999/2000. However it does run nicely in 16 MB of RAM which makes it useful for me because I want to see what happens when we run 100s of KVM instances :-) A few observations: (1) IDE DMA seems to cause problems. I get lost interrupts and general disk problems unless I boot the kernel with ide=nodma. (2) The kernel sees the default rtl8139 NIC but cannot seem to get any packets out of it. I had to switch to using ne2k_pci instead. (3) Heavy console activity hangs the virtual machine. This is a really weird and very annoying bug. (a) Serial console (-serial stdio) _also_ hangs under heavy activity. (b) At the point when the kernel hangs, the EIP is always at the same place, seemingly in the __best_copy_from_user function in the guest kernel. (c) The KVM monitor is still responsive. (d) (Now the strange bit ..) If I switch to the KVM monitor first and run my load tests - it doesn't hang! (e) However, qemu-kvm -nographic hangs under my load tests. (f) Plain qemu 0.9.1 doesn't hang.
